I was at Roche Harbor and noted that several of the tugs had Rocna anchors. I have also spoke to several owners who also suggest replacing the provided anchor with the Rocna? any reasons why Ranger does not use the Rocna? Any benefits to the provided anchor that I am not being made aware of?
Thanks

The Lewmar galvanized claw is about $100 at retail. The Rocna is $450. That's probably your answer on why it's not the default anchor from the factory. The Lewmar is probably great in some applications, but we have a lot of weather, tide, current, and other variability up here in the Upper Left and people want security. The Rocna is well suited to almost all bottom conditions, is easy setting, rights itself if upside down, etc.
 
+1 to dbsea. I would add that some folks never anchor so factory may see no reason to add cost. Also, among those who do, there are varying opinions -- so it makes sense to be reluctant to pick a single expensive solution.

FWIW we have a Rocna, too, and love it. OTOH some feel better with other anchors like Mantus, all stainless Ultra, etc.
 
If you decide to get the Rocna, i'd advise the Mantus swivel to go with it. They are a good set and you'll have a fantastic anchoring solution.

I would assume that the Lewmar windlass and Lewmar bruce anchor... and chain/rode, is a package deal from Lewmar.

The Rocna works great in the Pacific Northwest. It's really sticky.
 
I am one of those customers that am extremely happy with the Lewmar Bruce anchor and the way it fits the bow pulpit, sets and holds, and stays in when directions change in the sandy or soft mud bottoms where we anchor in the Great Lakes. We did upgrade to a stainless version (because it is easier to clean the mud off and looks much better with the stainless shield on the bow) and the Mantus swivel. Our second anchor is a lightweight Fortress which also has excellent holding power in our sandy bottoms.
 
When anchored for the night and a squall comes up you only have to be blown up on a beach or rocky shore once with the standard anchor. Rocna anchors are excellent, give peace of mind and a good nights sleep. They hold and do not drag or skip. If you plan on sleeping over night on a boat get the best anchor possible. I learned the hard way. Enjoy.
 
You may also want to take a look at a Manson Supreme. They are slightly less expensive than a Rocna, but a very similar style. What I also like about the Mason is the slotted feature on the shank. As always, no matter what anchor you may buy check to see that the size and fit will work with the current setup. Sometimes a little modification of the launch and bale are required.
 
I’m coming in on this a little late. What size Rocha would be appropriate for a R31CB?
And one more thing. Have any of you had an issue with the rode moving up over the corners of the bow pulpit during windy conditions where the boat swings dramatically? This is happening to me and it’s actually cutting the rope rode and basically making an awful racket so that we cannot sleep.
 
Hi second knotflying’s approval for the Manson Supreme with a Mantis swivel as it has worked flawlessly from the northwest waters to the north east waters of Maine in Canada to the rivers Tennessee and Kentucky, Florida waters and Bahamian waters, most adequate in all those conditions. Slight modifications to the launch platform and adding grooved bronze rollers that straightened the chain twist that eliminates wear on the chain gypsy and the Mantis swivel relives the chain twist. Money well spent on either a Manson Supreme or a Rocna anchor; add 100 feet a chain and you may sleep very soundly at night.
 
Hi Shabuba,
I'm, a Mantus user, but I believe the Rocna 15 is the size you'd want. (lots of Rocna users)

Are you using a bridle / snubber? The mantus one is excellent and should stop that from happening.

We have R31cb. We use a Rocna 15 and it works great set an forget unless it’s going to be really windy. Then we will set an anchor alarm. We have never had it drag. Sets quick.
We did have the situation you describe happen when we first got the boat. We got the mantus snubber and bridle.
Problem solved. We like anchoring and sleep well.
 
I think you can't go wrong with either, Rocna or Mantus. I have both, Mantus 35 as primary and Rocna 10 as secondary/spare anchor. Look at the anchor sizing table https://www.mantusmarine.com/mantus-anc ... or-sizing/ and decide what you need based on intended usage. I went with Mantus 35 as my cruising / storm anchor just in case I get caught in a 50kts+ wind. I hope it won't happen but if it will I know my anchor is suited for this. Also, Mantus swivel is a must have thing.
 
Rocna and Mantus anchors are very well made with ultra high holding capabilities. Our boat is much smaller than yours, a 25SC. We also have the Mantus Swivel and I highly recommend this no matter what anchor you choose.

On our little boat we utilize a Mantus 25 pound anchor along with the swivel and factory supplied 50 feet of 5/16 chain and like 160 feet of 5/8 3 strand nylon rode.

The 25 seems like over kill BUT, we trip south Florida, Great Lakes and upper Mississippi River. We have been caught anchored for the night in strong current, strong tidal swings and up to 35 knot winds … our Mantus kept us safe with no dragging. It sets extremely fast, even in hard packed sand, gravel bottoms, heavy sea grass etc.

My lighter factory anchor does not set as fast, is real hard to get a good set in sea grass ( like south Florida), or heavy wind and current.

Good luck with your search for a better anchor. If you spend many nights at anchor you may want to look at a Rocna or Mantus a little heavier … maybe like 30 pounds or more ( just one man’s opinion ).

Bob.
 
We also upgraded to the Rocna 15 for our last boat, the R25, and were very happy with it. Now that we have moved up to the R29, one of the first things we did was upgrade the anchor to the Rocna 15 again. We have done a lot of anchoring out over the years and have only dragged anchor once, which was my fault for setting too short of scope in a tight anchorage.

Our only issue is not with the anchor but with the rode rubbing the side plates of the bow roller structure, as someone else previously mentioned. My solution is to wrap a chafe protector around the rode at the bow roller. We use a nylon wrap-on protector about a foot long that velcros around the rope. After getting settled on anchor and cleated off, I pull the rode up a few feet, wrap the chafe protector on, and let it back out till the protector is on the roller. This stops any chafing or noise from the side pulls.
 
+1 also Rocna 15 (for C30) and Mantus bridle, plus Anchor Pro anchor alarm (works great). Also use the anchor alarm when doing a mooring buoy, adds a lot of peace of mind.
 
Many thanks to you all.I’ll get the Rocna and the snubber,etc. glad to know there is a fix in sight.
